I'm not sure of your issue with the Fuji RAW format, Albano. You say you print 5X4 jpegs at 1MB in size okay - have you tried printing a large/ fine jpeg at 10X8 ?
One thing you must remember is that the physical attributes of the sensor play a much larger role than most people understand. A file from a Canon D30 (3MP) will print up much better than a file (say) from a 5MP Sony DSC-F717 simply because the larger sensor of the D30 has less apparent noise than the much smaller sensor of the Sony.
